so we can say that the square root of 121 is: -11 and +11.

Is 324 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 324 is 18. Therefore, the square root of 324 is an integer, and as a consequence 324 is a perfect square.

The cube root of 324 is expressed as ∛324 or 3 ∛12 in the radical form and as (324)⅓ or (324)0.33 in the exponent form. The prime factorization of 324 is 2 × 2 × 3 × 3 × 3 × 3, hence, the cube root of 324 in its lowest radical form is expressed as 3 ∛12….Cube Root of 324.

Since 324 is a perfect square, it is rational number.

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

If you enter SQRT(-121) into a spreadsheet on your computer, you will get an error message saying something like “argument must be greater or equal to 0” because the square root of negative 121 is not possible. There is no real number multiplied by itself that will equal -121.
